NASA's Space Launch System Completes Preliminary Design Review

NASA has achieved a major milestone in its effort to build the nation's next heavy-lift launch vehicle by successfully completing the Space Launch System (SLS) preliminary design review.

NASA is developing the SLS and Orion spacecraft to provide an entirely new capability for human exploration beyond low-Earth orbit, with the flexibility to launch spacecraft for crew and cargo missions, including to an asteroid and Mars.
